Note
Either switch output or S0 interface!
Please note that either "DO" or S0 interface can function as switch output at a time!
Both functions cannot be used simultaneously!
To read out the energy values, switch output "DO” can be configured as an S0 interface
with the Interface Configuration Software. However, the same "DO” and "GND” connec-
tions are used.
3.3.3 Modbus-RTU interface "X1 IN" and "X2 OUT"
The Modbus RTU wires for registering communication with the subordinate controller
(PLC) are connected to “X1 IN” and “X2 OUT.” This is an example of how the connec-
tions can be assigned
•
Connection X1 IN:
PLC controller or up-circuit Modbus device
•
Connection X2 OUT:
Down-circuit Modbus device

Addressing
Via interface configuration software
The interfaces correspond to RS-485 are equipped as RJ-45 ports. The shielding is di-
rectly connected to FE (functional earth).
